Elevated c-di-GMP levels promote biofilm formation and biodesulfurization capacity of Rhodococcus erythropolis. [PDF]

Microb Biotechnol, 2021
In this work, we addressed the major hurdle of developing novel Rhodococcus erythropolis biocatalysts with improved biodesulfurization ability. To do so, we promoted Rhodococcus capability of forming a biofilm through the heterologous expression of a diguanylate cyclase that led to the synthesis of the biofilm trigger molecule cyclic‐di‐GMP (c‐di‐GMP).

Medium composition overturns the widely accepted sulfate‐dependent repression of desulfurization phenotype in Rhodococcus qingshengii IGTS8

Biotechnology and Bioengineering, Volume 120, Issue 10, Page 3092-3098, October 2023., 2023
Graphical Abstract An optimized culture medium, namely Medium C, significantly enhanced the biodesulfurization activity and biomass concentration of Rhodococcus qingshengii IGTS8, without modification of the natural biocatalyst. The supplementation of ethanol as a carbon source, combined with a unique selection of salt, metal, and vitamin solutions ...

Characterization of a dszEABC operon providing fast growth on dibenzothiophene and construction of broad‐host‐range biodesulfurization catalysts

Environmental Microbiology, Volume 24, Issue 4, Page 1946-1963, April 2022., 2022
Summary A new operon for biodesulfurization (BDS) of dibenzothiophene and derivatives has been isolated from a metagenomic library made from oil‐contaminated soil, by selecting growth of E. coli on DBT as the sulfur source. This operon is similar to a dszEABC operon also isolated by metagenomic functional screening but exhibited substantial differences:

Highly integrated adaptive mechanisms in Spiribacter halalkaliphilus, a bacterium abundant in Chinese soda‐saline lakes

Environmental Microbiology, Volume 23, Issue 11, Page 6463-6482, November 2021., 2021
Summary Soda‐saline lakes are polyextreme environments inhabited by many haloalkaliphiles, including one of the most abundant Spiribacter species. However, its mechanisms of adaptation are not ecophysiologically characterized. Based on a large‐scale cultivation strategy, we obtained a representative isolate of this Spiribacter species whose relative ...

Biodesulfurization Processes for the Removal of Sulfur from Diesel Oil: A Perspective Report

Energies, 2023
The presence of elevated levels of sulfur in diesel oil results in an increased sulfur content in the process stream, which poses significant risks to human health, animals, the environment, vehicles, and infrastructure.

The Alternating Growth of Bacteria within a Consortium During Desulfurization of Coal

Environment and Natural Resources Journal, 2022
Efforts to reduce organic sulfur in coal are taken through biodesulfurization by using desulfurization bacteria to release covalently-bound sulfur from the coal matrix. Coal is a complex hydrocarbon material that requires collaboration from more than one
